What is the common, pragmatic approach for handling large volumes of IoT sensor data in traceability systems?

Answer

Writing only the cryptographic hash of large data files (stored off-chain) onto the blockchain

Storing massive data directly on-chain is costly and slow; hashing the data allows the system to maintain an immutable integrity check without bloating the ledger.
